lactic

[หˆlaktษชk ]

Definition

Context #1 | Adjective

biochemistry, nutrition

Lactic refers to substances or processes related to lactic acid, a compound produced in the body during anaerobic respiration. This acid plays a crucial role in energy production, especially in muscles during intense exercise. Additionally, lactic is often associated with the fermentation process, particularly in dairy products where it helps in preserving food and enhancing flavors. Understanding lactic compounds is important in fields such as sports science and nutrition.

Synonyms

acidic, fermented, sour.

Examples of usage

  • Lactic acid builds up in muscles during strenuous exercise.
  • Fermented foods often contain lactic bacteria.
  • Lactic thresholds are vital for athletic performance.

Interesting Facts

Biology

  • Lactic acid is produced in our muscles during intense exercise when oxygen levels are low.
  • It plays a critical role in various metabolic processes, including energy production and oxidation.
  • The process of converting glucose into lactic acid is known as anaerobic glycolysis.

Health and Nutrition

  • Lactic acid can cause muscle fatigue, but it is also used in sports drinks to improve performance.
  • Some fermented foods contain lactic acid bacteria, which are beneficial for gut health.

Sports Science

  • Athletes often train their bodies to handle lactic acid better, allowing them to perform longer without fatigue.
  • Lactic threshold is the point during exercise at which lactic acid builds up faster than the body can remove it, affecting performance.

Pop Culture

  • Lactic acid often appears in discussions about fitness and bodybuilding, emphasizing the connection between exercise and muscle recovery.
  • The phenomenon of โ€˜runner's highโ€™ during long-distance running is frequently attributed to lactic acidโ€™s role in energy production.

Origin of 'lactic'

Main points about word origin

  • The term comes from the Latin word 'lac,' meaning milk, which reflects its discovery in sour milk products.
  • โ€˜Lacticโ€™ has been used since the early 19th century to denote compounds derived from lactic acid.

The term 'lactic' originates from the Latin word 'lac', meaning 'milk', reflecting the compound's discovery in sour milk. Lactic acid was first identified in 1780 by the Swedish chemist Carl Wilhelm Scheele, who isolated it from sour milk. The connection to milk is significant because lactic acid bacteria, responsible for fermentation, are crucial in producing various dairy products. Over time, the understanding of lactic acid has expanded beyond its dairy origins to encompass its role in metabolism and exercise physiology. The study of lactic acid has paved the way for research in areas such as sports science, nutrition, and biochemistry, highlighting the importance of lactic compounds in both health and food production.
